I'd love to see an open source YNAB clone... maybe this can be evolved in that direction! Well done.
EDIT: Looks like it's been updated to be an open source project: https://blog.financier.io/financier-is-now-open-source-bdfe9...
Like you say, there are some missing features, but it does what I need it to perfectly.
I used to use mint which was more automatic, but things rarely get categorized correctly, and by doing it by hand, I'm a lot more aware of my spending habits than if I just looked at some pie charts. I can still make pretty charts in excel if I ever wanted too.
I'm taking inspiration from YNAB, as it has a rich feature set. Also open source so that's a plus! Thanks!
